  We introduce a first-order theory Seq which is mutually in- terpretable with Robinson’s Q. The universe of a standard model for Seq consists of sequences. We prove that Seq directly interprets the adjuctive set theory AST, and we prove that Seq interprets the tree theory T and the set theory AST + EXT. This is a long version of a paper published in the proceedings from CiE 2024.

  There are sparse opportunities for direct measurement of upper stratospheric winds, yet improving their representation in subseasonal-to-seasonal prediction models can have significant benefits. There is solid evidence from previous research that global atmospheric infrasound waves are sensitive to stratospheric dynamics. However, there is a lack of results providing a direct mapping between infrasound recordings and polar-cap upper stratospheric winds. The global International Monitoring System (IMS), which monitors compliance with the Comprehensive Nuclear-Test-Ban Treaty, includes ground-based stations that can be used to characterize the infrasound soundscape continuously. In this study, multi-station IMS infrasound data were utilized along with a machine-learning supported stochastic model, Delay-SDE-net, to demonstrate how a near-real-time estimate of the polar-cap averaged zonal wind at 1-hPa pressure level can be found from infrasound data. The infrasound was filtered to a temporal low-frequency regime dominated by microbaroms, which are ambient-noise infrasonic waves continuously radiated into the atmosphere from nonlinear interaction between counter-propagating ocean surface waves. Delay-SDE-net was trained on 5 years (2014–2018) of infrasound data from three stations and the ERA5 reanalysis 1-hPa polar-cap averaged zonal wind. Using infrasound in 2019–2020 for validation, we demonstrate a prediction of the polar-cap averaged zonal wind, with an error standard deviation of around 12 m·s compared with ERA5. These findings highlight the potential of using infrasound data for near-real-time measurements of upper stratospheric dynamics. A long-term goal is to improve high-top atmospheric model accuracy, which can have significant implications for weather and climate prediction.

  We study a degree structure on representations of irrational numbers (typical examples of representations are Cauchy sequences, Dedekind cuts and base- 10 expansions). We prove that the structure is a distributive lattice with a least and a greatest element. The maximum degree is the degree of the representation by continued fractions. The minimum degree is the degree of the representation by Weihrauch intersections.

  Let $X\subset \mathbb P^d$ be a $m$-dimensional variety in $d$-dimensional projective space. Let $k$ be a positive integer such that $\binom{m+k}k \le d$. Consider the following \emph{interpolation problem}: does there exist a variety $Y\subset \mathbb P^d$ of dimension $\le \binom{m+k}k -1$, with $X\subset Y$, such that the tangent space to $Y$ at a point $p\in X$ is equal to the $k$th osculating space to $X$ at $p$, for almost all points $p\in X$? In this paper we consider this question in the \emph{toric} setting. We prove that if $X$ is toric, then there is a unique toric variety $Y$ solving the above interpolation problem. We identify $Y$ in the general case and we explicitly compute some of its invariants when $X$ is a toric curve.

  We consider families of $(n-r)$-dimensional linear spaces parameterized by a projective variety $X\subset \mathbb P^n$ of dimension $r$. The envelope of the family is the branch locus of the map from the total space of the family to $\mathbb P^n$. The \emph{evolute} of $X$ is the envelope of the family of normal spaces. We study the singularities of the evolute and evaluate the corresponding Thom polynomials to get numerical formulas. In particular, we verify Salmon's formulas in the case of curves and surfaces.

  A classical problem in enumerative geometry is to determine how many plane curves of given degree and with given types of singularities pass through some fixed points. For example, there is 1 non-singular cubic passing through 9 points, but 12 singular cubics passing through 8 points. Such curve counting problems have received new attention because of their appearance in string theory in theoretical physics. There is currently no closed formula solution to the above general problem. However, as I will explain, in some cases one can determine the generating function: a formal power series whose coefficients are the desired solutions.

  Accurate estimation of impact sensitivity is crucial for safe production, handling, storage and transport of energetic materials. Indeed, molecular characteristics will affect sensitivity, and for solid materials, factors like particle size, lattice defects and morphology also play a role and make reproducibility difficult. As various synthesis and recrystallisation methods may lead to differences in crystal properties, it is important to determine the impact sensitivity whenever an energetic material is prepared. Of particular interest is the median ℎ50, namely the impact energy level at which there is a probability of 50% of an explosion occurring. This value has been shown to correlate with quantum chemical properties of the energetic material in question, providing insight into the underlying causes which govern sensitivity. However, in practical applications, it may be more important to estimate extreme values like the 99% quantile ℎ99. In addition to providing point estimates, we would like to derive confidence intervals to address their uncertainty. In this work, we cover the most common methods for constructing such confidence intervals (the delta method, Fieller’s theorem and the likelihood-ratio test) and compare their performance on sensitivity data via simulations. Our experiments indicate that Fieller’s theorem is the superior method, and we therefore use it to construct confidence intervals for ℎ50 and ℎ99 for cyclotetramethylene- tetranitramine (HMX), using new data. Based on our results, we formulate recommendations for researchers measuring sensitivities of synthesised molecules.

  We address the following interpolation problem: given a variety X in projective n-space, does there exist a variety Y in the same space, containing X, and such that the tangent space to Y at almost any point of X is equal to the kth osculating space to X at that point? We give a positive answer in the case that both X and Y are toric varieties. The special case where X is the rational normal curve is studied, in particular for k=2 and k=n-1.
